>> On Windows, the test java/lang/ProcessHandle/InfoTest.java can fail when run as user that is member of the Administrators group. In that case new files are not owned by the user but instead by BUILTIN\ADMINISTRATORS. This breaks the assumptions of the test's whoami check. My suggestion is to cater for this case and don't fail the test but write a warning message to stdout that a whoami check is not correctly possible.

A bit late due to a US holiday. Looks good.
